Description

Technical Field

[0001] This utility model is a device for drying and retracting fire hoses, belonging to the field of fire protection facilities. Background Technology

[0002] After each firefighting operation, firefighters often spend a significant amount of time and manpower washing and carrying fire hoses to suitable floors to dry them from top to bottom. Once completely dry, the hoses must be brought back to the ground. This traditional drying method is time-consuming, labor-intensive, and inefficient, especially for urban fire stations with large jurisdictions and heavy firefighting workloads. Therefore, drying fire hoses after returning to the station becomes a major challenge for firefighters. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for drying and rewinding fire hoses to solve the problems mentioned in the background technology. This utility model realizes the drying of fire hoses when rising and the automatic rewinding while descending, which are carried out and finished simultaneously. It is simple to operate and saves labor and time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for drying and retracting fire hoses, comprising a mobile hydraulic pump station. A track section is mounted on the top of the mobile hydraulic pump station. Two track sections are slidably installed within the first track section. A third track section is slidably installed on the side of the second track section opposite to the first track section. A hydraulic cylinder is mounted on the top of the mobile hydraulic pump station. The movable end of the hydraulic cylinder is connected to the bottom of the second track section. Two sets of first wire rope loops are rotatably installed within the second track section via rope pulleys. One vertical part of the rope loop remains in a fixed relative position with the top of a section of track, and the other vertical part of the first wire rope loop remains in a fixed relative position with the bottom of a three-section track. Two sets of second wire rope loops are installed inside the three-section track via rope pulleys. A take-up beam is fitted on the three-section track and is slidably installed with the three-section track. One vertical part of the second wire rope loop remains in a fixed relative position with the take-up beam, and the other vertical part of the second wire rope loop remains in a fixed relative position with a section of track. A take-up device for winding up the fire hose is installed on the take-up beam.

[0005] Furthermore, the take-up component includes a turntable. Multiple equidistant turntables are rotatably mounted on the side of the take-up beam opposite to the three-section track. End sprockets are located at both ends of the side of the take-up beam opposite to the turntables. Two symmetrically arranged main sprockets are located at the center of the side of the take-up beam opposite to the turntables. Multiple double sprockets are located between the main sprockets and the end sprockets. The double sprockets, main sprockets, and end sprockets are connected and fixed to the corresponding turntables via connecting shafts. Between two adjacent double sprockets, one double sprocket closer to the main sprocket is connected to... The main sprockets are connected to each other, and the end sprockets are connected to the double sprockets furthest from the main sprockets via drive chains. The main sprockets are connected to the upper sprocket via a one-way ratchet. A lower sprocket is provided on the lower side of the upper sprocket. The lower sprocket is rotatably connected to the take-up beam. A vertically arranged stationary chain is provided between the lower sprocket and the upper sprocket. The lower sprocket and the upper sprocket are located on both sides of the stationary chain. Both ends of the stationary chain are connected and fixed to three sections of track. Two crossbars for winding fire hoses are installed on the side of the turntable away from the take-up beam.

[0006] Furthermore, the side of the track section facing away from the three-section track is provided with multiple connecting seats for mounting on the wall, and the two ends of the connecting seats are respectively mounted on two parallel sides of the track section.

[0007] Furthermore, the mobile hydraulic pump station is equipped with a fence on its upper side to restrict the position of the lower end of the fire water bag. The fence has a "C" shaped structure, and both ends of the fence are connected and fixed to a section of track.

[0008] Furthermore, the turntable is provided with a wheel for supporting the fire hose on its lower side. The wheel is rotatably connected to the hose reel beam, and the cross-section of the wheel is "I" shaped.

[0009] Furthermore, multiple supports are evenly installed within the track section, and the cylinder body of the hydraulic cylinder is connected to the supports.

[0010] The beneficial effects of this utility model are:

[0011] 1. The system is installed in the fire station against a wall with ample sunlight. Utilizing the principle of a three-section track, the main power is provided by a hydraulic cylinder driven by a mobile hydraulic pump station. The hydraulic cylinder is located in the middle of one section of the track. The hydraulic cylinder pushes the two sections of the track to move up and down. The first wire rope loop connects to the three sections of the track to move up and down synchronously. At the same time, the second wire rope loop connects to the hose reel beam to move synchronously. After one end of the fire hose is restricted on the hose reel beam, the fire hose can be raised to a high place and deployed in one go without the need to climb and hang it layer by layer.

[0012] 2. The take-up beam moves up and down within three sections of track for one cylinder stroke. Two stationary chains are arranged vertically. Two main sprockets are arranged on the take-up beam and rotate on the stationary chains. A one-way ratchet is designed on the main sprockets. When the cylinder rises, the one-way ratchet rotates freely. When the cylinder descends, the one-way ratchet automatically engages. Utilizing the weight of the equipment and the fire hose itself, and the up-and-down movement of the three sections of track, the transmission of the upper sprocket, lower sprocket, and stationary chains drives multiple turntables to move simultaneously, achieving purely mechanical take-up of the fire hose. This makes the equipment more reliable and lower in cost. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a device for drying and retracting fire hoses, comprising a mobile hydraulic pump station 1, a track 10 mounted on the top of the mobile hydraulic pump station 1, a second track 9 slidably mounted inside the first track 10, a third track 7 slidably mounted on the side of the second track 9 opposite to the first track 10, a cylinder 8 mounted on the top of the mobile hydraulic pump station 1, the movable end of the cylinder 8 connected to the bottom of the second track 9, two sets of first wire rope loops 12 rotatably mounted inside the second track 9 via rope pulleys, one vertical part of the first wire rope loop 12 maintaining a fixed relative position with the top of the first track 10, and the other vertical part of the first wire rope loop 12 maintaining a fixed relative position with the bottom of the third track 7, and two sets of second wire rope loops rotatably mounted inside the third track 7 via rope pulleys. The rope loop 13 and the three-section rail 7 are fitted with a take-up beam 2 that is slidably installed on the three-section rail 7. One vertical part of the second wire rope loop 13 and the take-up beam 2 remain in a fixed relative position, and the other vertical part of the second wire rope loop 13 and the two-section rail 9 remain in a fixed relative position. It is placed against a wall with sufficient sunlight in the fire station. Utilizing the principle of the three-section rail, the main power is provided by the hydraulic cylinder 8, which is driven by the mobile hydraulic pump station 1. The hydraulic cylinder 8 is located in the middle of the first section rail 10. The hydraulic cylinder 8 pushes the two-section rail 9 to move up and down. The first wire rope loop 12 drives the three-section rail 7 to move up and down synchronously. At the same time, the second wire rope loop 13 connects to the take-up beam 2 to move synchronously. After one end of the fire hose is restricted on the take-up beam 2, the fire hose can be raised to a high place and unfolded in one go without climbing and hanging from each floor.

[0023] See Figures 1-6Multiple equidistant turntables 5 are rotatably mounted on the side of the take-up beam 2 facing away from the three-section track 7. End sprockets 15 are located at both ends of the side of the take-up beam 2 facing away from the turntables 5. Two symmetrically arranged main sprockets 20 are located in the middle of the side of the take-up beam 2 facing away from the turntables 5. Multiple double sprockets 17 are located between the main sprockets 20 and the end sprockets 15. The double sprockets 17, main sprockets 20, and end sprockets 15 are connected and fixed to the corresponding turntables 5 via connecting shafts. The double sprockets 17 are positioned close to the main sprockets 5. One of the double sprockets 17 of the wheel 20 is connected to the main sprocket 20, and the end sprocket 15 is connected to the double sprocket 17 furthest from the main sprocket 20 via a drive chain 16. The main sprocket 20 is connected to the upper sprocket 19 via a one-way ratchet 21. A lower sprocket 18 is located below the upper sprocket 19. The lower sprocket 18 is rotatably connected to the take-up beam 2. A vertically arranged stationary chain 14 is provided between the lower sprocket 18 and the upper sprocket 19. The lower sprocket 18 and the upper sprocket 19 are located on both sides of the stationary chain 14. Both ends of the turntable 5 are connected and fixed to the three-section rail 7. Two crossbars 4 for winding the fire hose are installed on the side of the turntable 5 facing away from the winding beam 2. The winding beam 2 moves up and down within the three-section rail 7 for one cylinder 8 stroke. Two stationary chains 14 are arranged vertically. Two main sprockets 20 are arranged on the winding beam 2 and rotate on the stationary chains 14. A one-way ratchet 21 is designed on the main sprockets 20. When the cylinder 8 rises, the one-way ratchet 21 idles; when the cylinder 8 descends, the one-way ratchet 21 automatically engages. Using the weight of the equipment and the fire hose, the three-section track 7 moves up and down. The transmission of the upper sprocket 19, the lower sprocket 18 and the stationary chain 14 drives multiple turntables 5 to move simultaneously, realizing the purely mechanical winding of the fire hose. This makes the equipment more reliable and lowers the cost. The turntable 5 is equipped with a wheel 3 for supporting the fire hose. The wheel 3 is rotatably connected to the winding beam 2. The cross-section of the wheel 3 is "I" shaped, so that the fire hose overlaps on the wheel 3. In this way, the wheel 3 and the turntable 5 cooperate with each other to facilitate the winding of the fire hose.

[0024] See Figure 1 and Figure 2 On the side of a section of track 10 facing away from the three sections of track 7, there are multiple connecting seats 11 for mounting on the wall. The two ends of the connecting seats 11 are respectively mounted on two parallel sides of the section of track 10. Multiple supports are evenly installed inside the section of track 10. The cylinder body of the hydraulic cylinder 8 is connected to the support. The support improves the stability of the hydraulic cylinder 8 installation and allows the connecting seats 11 to be mounted on the wall, thereby improving the stability of the overall structure. The upper side of the mobile hydraulic pump station 1 is provided with a retaining rod 6 for limiting the position of the lower end of the fire hose. The retaining rod 6 has a "C" shaped structure. Both ends of the retaining rod 6 are connected and fixed to the section of track 10. Under the restriction of the retaining rod 6, the range of motion of the lower end of the fire hose is limited.
